Seems there's lot of mess in the company all because of Microsoft or name it greed or late stage capitalism but still something tells me GitHub is just too important to lose dominance in next few years, after that if any other company takes over it'll probably be gitlab but it's really hard to speculate on this kind of things, I hope Microsoft leaves GitHub alone, they probably will fix themselves, lot's of developers depend on Github and migration is not easy thing for big repos I expect.
